Mix Your Own Argoshield MIG welding TIG 

Thanks, glad your gonna give it a go 👍

😂 sorry about that mate

@@CarJunkeez no worries, this video was worth the discomfort 😎 haha

Thanks 🙏 yes I looked into mixing straight into another bottle but the high pressures and expensive equipment put me off a little, this seams to work well for my needs though 👍 cheers

Was that a hose going from say your Co2 tank through the digital gauge & directly into the empty tank at 20bar. Then after the Co2 is finished repeat with argon at 180bar? Or does it have to be done together? I'm interested in having the capability of doing this, even if I 90% of the time I use Argos shield, I'd like to have the option as a fall back plan.

Thanks mate, same here I couldn’t find any videos so thought I’d make one 👍

Yes I totally understand what you mean, just 2 solenoid valves wired in parallel to the internal one in the welder. I must say it would be beneficial when TIG for then first couple of seconds. Cheers 👍

@@CarJunkeez I have never tried mixing without the extra solenoid valves, it may be overkill. The way you are doing it with identical regulators, and I assume the low pressure gauge is set the same on both, may work perfectly. Sometimes I overthink these things and I don't want to discourage anyone from trying the mixing as you have presented it here. The results are what matters. It is something to keep in mind if there is some weirdness in the first few seconds of welding.

I really like this ideal but seems maybe a little expensive/difficult to setup? Do you think a small expansion chamber would be a cheaper/easier alternative with similar results? I was thinking something around 10 cu in, made from some PVC pipe and have the two gas supply inlets at one end and the outlet at the other end. I guess since you are having them feed at different pressures you would still need a check value which seems like with the solenoids are doing.

Thanks man appreciated 😁 yea using the flow rate and maths you right you can mix quite accurately. The mixer tap is pretty much the same as the torch taps too. Just watched you videos on your welding exams over there, looks awesome bro, you have some good equipment over there 😮👍

@@CarJunkeez Yes the welding schools at BCIT and Kwantleen here in Vancouver Lower Mainland are the best! Yes I learned there a lot! Thanks. Was wondering there at your setup. Might flashback arrestors be necessary? (those valves that allow gas to flow just in one direction) I'm thinking if one cylinder is more emptier than the other therefore the cylinder with more pressure will push the gas into the one cylinder with less pressure maybe!? What do you think?

I’ve not had any problems as yet but I’ve not run low on gas so possibly when low, I suppose it wouldn’t do any harm in fitting them for peace of mind 👍

@@CarJunkeez I made my setup. Works fine without check valves ( Not flash back arrestors). The only difference that I made is I've put a bigger CO2 cylinder in case there might be a need to weld with straight CO2. Later on I have to make it more crazier by mixing 3 gases: Ar CO2 and Helium for stainless steel wire. But that is just for later on. For now I'm good with what I have.

Awesome man, yea good move on the 3 way mix too, some people over here use the helium on titanium exhaust. We tend to only use the small co2 bottles as we get them cheap as they are pub gas for bear 👍

Thanks 🙏

Hi, thanks for watching. There is no need for check valves, just the Y adapter is sufficient as the pressure delivery is very low 👍

Mark Smith it works out cheaper to pal and the Co2 really does last a long time even though the bottles small

Hi, no I don’t use another as this will affect the consistency or the other 2 if adjusted. I just use the 2 and add both levels together to give me the overall flow rate at the torch 👍

Make sure you haven’t got the flow to high, but yes it can be a problem freezing and some regulators can handle it better than others.

I have had CO2 regulators frost up, but only when running a lot of volume while doing silly things like running an impact wrench. I have never had one frost up on my MIG setup. You might be running too much CFH by mistake. It's not likely, but some CO2 bottles have a siphon tube to draw liquid from the bottom of the cylinder, that would do it. Look on the tank for the word "siphon". I assume you have the tank upright. You could put a fan on it perhaps.

That’s pretty close yea but can be different from MIG to TIG and mixed steels so play about with it 👍

audioshooter hi, sorry if you find the video incorrect, I’ve used this configuration for a while now with no problems so works for me, I only tend to Mig sheet steel and if I was to weld 1/4 inch or thicker I tend to use stick, but thanks for the info it’s very useful

Hi, I got the mixer taps and some fittings fro R-tech same place I got my welders from but I had to get the other fittings from ebay like the Y adapter 👍

@@CarJunkeez what do i need to search for as ive tried diffrent terms on ebay and got everything i dont want lol

This is the Y adapter tap www.r-techwelding.co.uk/double-outlet-gas-valve-y-piece-right-hand/ And this is the Argon flow meter www.r-techwelding.co.uk/argon-flow-meter/ And this is similar to the Y brass connector rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.co.uk%2Fulk%2Fitm%2F372751506709 Hope this helps pal 👍

Thanks, yea that’s correct 👍

Hi, It’s being mixed after the regulators so very low pressure and no way of going back past to the bottle 👍 cheers

They’d only do that if you was trying to mix before the regulator’s but as it’s being mixed after the regulator’s at a low pressure there’s no need for check valves as there’s no way the low pressure gas will force back into the regulator 👍
